DRI'K Mixen;

To all whomy t may concern.'

Be it known that I, SHAKiR S.l JERWAN, a citizen of the UnitedStates,- and a residentl of the city of New' York,l borough of' Manhattan', in' the county and State o- New York, have invented new and useful Improvements* in Drink Mixers; ofl which the' following is a full,- clear, and exact 2 description.

This invention relates to drink` mixers' primarily designed for use in' preparing drinks sold over? so'da Water fountairif couriters.

The-general'- object of the invention istheA provision of a simple and eicient devicefor giving drink containers a motion capable of thoroughly mixing: the ingredients of any drink that may" ber contained therein.

A further object of the invention is' the' provision' of al drinlr container having' an oscillatory ar1n= for giving ag drink container a drink-miningmotion provided Withlmeans' :for stopping the oscillatory arm inI ay predetermined position.

These' objects are' accomplished by pivotally mountingv onf a frame an'arin'equipped with 'a drink container holder, associatingl Witlr theV pivotally mounted arnr means for giving? it an' angular' movement about" its pivot point so as to move' the" drink` con'- tainer holder back andi forth along'an are4 of :n circle, and providing? iny conjunction With the operating" mechanism`r means" for" stopping the" pivot-ally mounted' arm: in a predetermined position. x

These and other objectsof the invention will be' more" clearlyl understood from? the following detailed description and? accom# pany'ing drawings:

Figuren is a side' elevation' ci the drink m'irenwitli`y a portion of the 'casing 'cut'y away to slio'vv its construction;

colla-r 15.2 nter'posed betvve'en this collar 15' and the bell crank 18 is acoil spring 14Cl provided with' outturned ends which' prof ject intoopenings provided inthe collar 15 and the bell crank 13. The tensionE on-` the spring llfmay be variedl by adjusting the collar l5.

Formed on the outer endVl of one arm of the bell crank 13 isa depending L-shaped arm 17 on thev front side of: which ar guide 19v is provided. Carried by the lower portion of they L-shaped arm' is a dish-shaped member 18 for receiving any drinky container. is a slide 2O provided Withmeans'or clampl ing it'in any desired position on the guide A; second lbshaped armE 22 is carried by the f slide 20 and has attached thereto a second dish-shaped'member 21' located in'- alinement Witli the dish-shaped member 18. This dish-shaped member 21 serves to grip any drink container placed in position on thev through' a pulley 28 lined toT the shaft of the prime mover anda belt 30. The motion transmitted tothe' ivorm" gear' 23`fr01n the prime mover 271is'conveyed to the'bell crank lthrougfhf a rigid linkl 33, connected to a crank pin 34 provided onthe Worml gear 23' ati af distance from the center.

lRotat'a'bl v monntedin the basel() is apos't 35 operated by means of an arm 38; A' lever having ain' offset therein is cari-iedlby tli'epost the' oiiset' being' rotatably positioned inanfopening iiii'theA post. This' ylever preseiitsan aifin on o'iielside'oiY tlie posti and an arn'i 3.9"011" the' other, Mbiinted on the arm' S7 isi a" brake" block 36 which* col operates with drum 29 fined to thepullev 28"for stopping;r thepriniefmover 27. This brake bloek'` 36'l is normally r'eta'iiiedl out of 41 which" is connected betxveeii the arm: 37 and' a pin j 'xe'd to the' operat'injgl arn'- 38';

The aiim; 3'9y extends between the'Vl standard Movably mounted on the guide 19 Fixed to ai common shaft llO an inactive position by a pin 40 fixed to the standard 11. By rotating the post 35 the arm 39 is moved into the position shown in Figure 3 where it lies in the path oi movement of an extension of the crank pin 34. The rotation of the post also carries the brake block 36 into aline-ment with the drum 29.k Consequently when the arm 39 is forced downward by the crank pin 34 the brake block 36 is forced into engagement with the drum 29, stopping the prime mover 27. The crank pin 34 is so positioned on the worm gear 23 that it operates the braking mechanism to stop the prime mover 27 when the arm of the bell crank 13 carrying the drink container receiver reaches a horizontal position, as shown in Figure 1. The operating mechanism of the primo mover of the drink mixer is enclosed by a casing 32.

Referring to Figure 3, two electrical contact members-42 and 43 are mounted in the base 10 and insulated therefrom. The motor 27 is supplied with electrical energy through conductors 44 and 45 connected to the contact members 42 and 43. These contact members 42 and 43 are bridged b v a conductor mounted on the arm 38 and insulated therefrom. The bridging of the contact members 42 and 43 takes place when the arm 38 is rotated counterclockwise, throwing the brake into an inactive position. The circuit for supplying the motor 27 is broken when the arm 38 is rotated clockwise, throwing the brake into an active position.

The operation of the drink mixer is as follows:

When the prime mover is setI inoperation it drives the wormI gear 23 through the pulley 28, belt 30, pulley 31 and worm 25. The motion of the worm gear 23 is conveyed to the bell crank 13 through the rigid link giving the bell crank an oscillatory movement about the axle 12. |This angular movement of the bell crank gives any drink container mounted in the drink container receiver a drink-mixing motion which serves to agitate the ingredients enclosed in the container. `When it is desired to stop the operation o' the drink mixer the operatingarm 38 is rotated, throwing the arm 39 into the path ot the extension of the crank pin 34 and at the same time breaking the circuit supplying the motor 27. The arm 39 is forced downward, raising the arm 37 and brake block 36. This operation of the arms 39 and 37 takes place when the arm of the bell crank carrying the drink container receiver has reached approximately a horizontal position. Vhen the brake block 36 is thrown into engagement with the drum 29 b-y the operation of the arms 39 and 37 the prime mover is stopped, stopping the bell crank in the desired position. Upon the swinging of the arm in the opposite direction to release the drum 29 the spring 41 drives the brake bloc-k downward away Jfrom the drum 29.

The spring 14 assists in the operation of the bell crank. When the bell crank is moved downward the spring is energized and tends to raise the bell crank. Consequently as soon as the bell crank starts on its upward movement the spring 14 assists the prime mover in operating the bell crank. The energizing ot the spring by the bell crank as it moves downward gradually absorbs the momentum of the bell crank and eliminates the possibility of shocks to the drink mixer when the bell crank reaches the limit of its downward motion.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention I do not limit myseli` strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as defined in the appended claims.
